Genetic variation alters response to common anti-clotting drug

...its and needle pricks to determine an individual's ideal dose. Scientists know that variations in a gene encoding the CYP2C9 enzyme that metabolizes warfarin account for about 10 percent of the difference in people's responses to the drug, but tests for these genetic variations are not routinely performed....

Corn grain mould used as pesticide

...eloping countries, particularly, this would be the ideal strategy to get the upper hand of the aflatoxin problem," Professor Sikora thinks. He has had quite a lot of experience with combating tropical plant diseases. For two years the Bonn team, together with colleagues from the IITA in Benin and Nigeria,...

Purdue's gold nanorods brighten future for medical imaging

...ght in this spectral region. The gold nanorods are ideal for a type of imaging called "two-photon fluorescence," which provides higher contrast and brighter images than conventional fluorescent imaging methods. Photons are the individual particles that make up light. In two-photon fluorescence, two photon...

Bone marrow stem cells may heal hearts even years after heart attacks

...ime, yet more research is required to identify the ideal route of implantation, and the type of cell transplantation that is most efficient for regenerating damaged myocardium." Roberto Bolli, M.D., F.A.C.C., from the University of Louisville in Louisville, Kentucky, who co-authored an editorial appearing...

The earliest animals had human-like genes

...something like a 'living fossil'" This makes it an ideal model for evolutionary comparisons to find out what the common ancestors of humans, flies and worms were like." Until quite recently, such comparisons could only be made by looking at physical characteristics such as the structure of bones, teeth, o...

Rutgers researchers scientifically link dancing ability to mate quality

...al symmetry in that population. The test group was ideal for a scientific study of dance, since in Jamaican society, dancing is important in the lives of both sexes. The dancers ranged in age from 14 through 19, and each danced to the same song, popular at the time in Jamaican youth culture. The researcher...

New understanding of regeneration gained by Forsyth scientists

...e powerful regeneration capability that makes them ideal for studying this process. When the worms are cut in half, the bottom section of the worm grows a head and the upper section a tail. Scientists have suspected that the ability of previously adjacent cells (on either side of the cut) to adopt radical...

Fitting in: Newly evolved genes adopt a variety of strategies to remain in the gene pool

...g functional roles." Yeast metabolism provides an ideal model for investigating the functional basis for gene duplication because a large proportion of genes involved in this biological process have been duplicated. Of the 672 genes involved in yeast metabolism, 295 genes can be classified into 105 famil...

Algal protein in worm neurons allows remote control of behavior by light

...ectly by certain wavelengths of light, making them ideal for remote control in the laboratory. In their experiments, the researchers took advantage of the light sensitivity of the algal channel protein by introducing expression of a modified form of ChR2 in specific C. elegans neurons and muscle cells. Th...

Worms know bad food when they smell it

...ttle as five minutes. But while some bacteria make ideal worm food, others are toxic. "The worm swallows them and then they establish an infection inside the worm's gut and they proliferate there. It's exactly like food poisoning," Bargmann explained. If the worm has ingested enough of the bacteria, it c...

Sleeping sickness parasite shows how cells divide their insides

...has only one of each internal organelle, making it ideal for studying processes of more complex organisms that have many copies in each cell. When thinking about how cells divide, doubling and separating DNA in chromosomes is often the focus. Equally important is the way a cell prepares its internal orga...

Portable cocaine sensor developed at UC Santa Barbara

...y (JACS), the authors state, "Cocaine serves as an ideal and representative target for testing new analytical techniques due to pressing needs for its rapid detection in law enforcement and clinical settings." The sensor can be housed in supporting electronics that are the size of a small hand-held device....

Screening blood for West Nile virus

... contaminated blood for a reasonable price. (In an ideal world, cost would not matter when it comes to protecting human life and health, but in reality there is limited money available for public health measures. Studies such as this one are therefore essential to help politicians decide how to spend their...

Junk DNA may not be so junky after all

...the zebrafish ret gene. Zebrafish have become the ideal system for doing these types of large scale studies. They are small - only about a half inch in length - they grow quickly, and are relatively inexpensive to maintain compared to mice or rats. "Zebrafish are the only vertebrate embryo you can even th...

Infused spleen cells found not to impact islet recovery and reversal of type 1 diabetes in mice

Genome sequencing is for ecologists, too

...genome (a mere 200 million base pairs) makes it an ideal organism for laboratory and field studies of how environments influence -- and how they're influenced by -- an organism's genetics. The animals are common in lakes and ponds and have been used to monitor the health of aquatic environments. Members of...
